First, I have not read all of the posts yet. But I want to clear up some misinformation.
I live in Colorado. Less than an hour away from Boulder. I have lived in Colorado my entire life. I have watched Columbine and the Aurora theater shooting as they unfolded.
In the US we have a constitutional right to bear arms. My husband is a gun collector and has multiple. He would lay down his life to protect that right. He has in fact served his country in the military to defend all of our rights, including the right to say you dont like guns. I don't expect anyone in other countries to understand and honestly I don't care. His guns have never killed anyone, nor will they. They are kept locked in a safe separate from the ammunition, in the basement which is also locked.
This shooter in Boulder was mentally ill. His family knew he was paranoid and delusional at times. His may have been bullied, but his mental health issue was not the result of bullying.
In the US, it is required that people buying guns complete a background check. It is called the Brady law. There are loopholes however, which Colorado has moved to close.
In Colorado you must complete a background check for all gun purchases.
In Colorado, we have a law against high capacity magazines.
In Colorado we have Red Flag Laws which would take guns away from people who are mentally unstable.
His family saw him "playing" with the gun 2 days before the shooting. They took it away from him and put it in his bedroom.
One phone call from his family would have stopped this and saved 10 lives.
What other laws would you all suggest? Murder is illegal and yet...
We don't have a gun problem in the US. We have a mental health problem. IMO we also have a media problem because they use these types of events for ratings.
Also, our president can not just outlaw guns. He is not an emperor. We have checks and balances. Congress makes the laws.
Before anyone starts putting misinformation out there, please know the facts. If you are unfamiliar with the way the US works, please educate yourself.
